- the locking structure of the switch device can be operated with less strength.
- the entire structure of the locking structure of the switch device can be completely enclosed.
- a conventional switch device or switch indication device is applied to an electrical, electronic and automatic control system for an operator to operate the machine or power on/off the system.
- a conventional switch device discloses a part installation structure, in which a support body is connected with a pushbutton (an operation section) and a switch (a wire connection module).
- the support body is formed with a perforation for receiving the pushbutton.
- a ring-shaped rotary body is pivotally disposed on the perforation of the support body.
- a raised section is disposed on inner circumference of the rotary body.
- a lever protrudes from the outer circumference of the rotary body to extend into a protection section positioned on one side of the support body. The lever can drive the raised section of the rotary body to latch with a groove section formed on outer circumference of the pushbutton into a locked state, whereby the pushbutton is assembled with the support body.
- the engagement section at the rear end of the lever is engaged with the engagement section in the protection section so as to locate the lever.
- the lever can be shifted to disengage the engagement section of the lever from the engagement section of the protection section.

- FIG. 7 is a sectional view according to FIG. 6 , showing an unlocking use of the present invention.
- the locking structure of switch device of the present invention includes a connection seat 1 and a shift body 2 assembled with the connection seat 1 .
- the connection seat 1 is formed with a main body assembling hole 11 .
- the shift body 2 is formed with a perforation 20 in communication with and in alignment with the main body assembling hole 11 .
- the main body assembling hole 11 and the perforation 20 serve to together receive an operation section main body 3 to assemble the main body 3 with the connection seat 1 .
- An operation section 31 is received and disposed in the main body 3 for an operator to press or rotate so as to control the switch device into a closed-circuit state or an open-circuit state.
- the main body 3 has a shaft section 32 and a channel 33 formed on the shaft section 32 .
- a latch section 12 is disposed on the bottom section of the connection seat 1 for latching with multiple side by side arranged wire connection modules.
- the wire connection modules pertain to prior art and are thus not shown).
- Electrical contacts and wire connection components are mounted in the wire connection modules for connecting with external conductive wires. Via the operation section 31 , an operator can drive the wire connection components to control the electrical contacts into an open-circuit state or a closed-circuit state.
- an arm 14 protrudes from one side of an upper section 13 (or top section) of the connection seat 1 .
- a restriction section 15 is formed on the arm 14 .
- a sidewall 16 is disposed on one side of bottom face of the arm 14 .
- the restriction section 15 protrudes from the bottom face of the arm 14 to the bottom section (or the latch section 12 ) of the connection seat 1 .
- Two sides of the restriction section 15 are respectively formed with a sloped section 151 and a stop wall 152 facing the sidewall 16 .
- An insertion cavity 17 is defined between the stop wall and the sidewall.
- a support section 153 is formed between a start end of the sloped section 151 and the stop wall 152 .
- the shift body 2 is assembled with the upper section 13 of the connection seat 1 .
- the shift body 2 includes an annular section 21 , a shift section 23 protruding from outer circumferential wall of the annular section 21 and a mouth section 24 formed on the shift section 23 .
- the annular section 21 is formed with a perforation 20 and multiple insertion blocks 22 formed on inner wall of the perforation 20 .
- a lever member 25 is received in the mouth section 24 .
- a fulcrum section 251 is disposed at the middle of the lever member 25 .
- the fulcrum section 251 is connected with the inner wall of the central portion of the mouth section 24 .
- Two ends of the lever member 25 are respectively formed with a ridge section 252 and a push/press section 253 .
- the push/press section 253 forms a leverage structure relative to the ridge section 252 .
- the shift section 23 , the mouth section 24 and the lever member 25 of the shift body 2 can be integrally made of plastic material.
- the fulcrum section 251 has elasticity and is flexible to serve as the swinging fulcrum of the lever member 25 . Therefore, with the fulcrum section 251 serving as the leverage fulcrum, the push/press section 253 and the ridge section 252 at two ends of the lever member 25 can relatively swing in reverse directions.
- the ridge section 252 and the push/press section 253 respectively have an elastic motional range. Accordingly, when an operator presses the push/press section 253 , the lever member 25 will drive the ridge section 252 to swing in a reverse direction by way of leverage with the fulcrum section 251 serving as the leverage fulcrum.
- the shift body 2 when the shift body 2 is assembled with the connection seat 1 with the shift section 23 misaligned from the arm 14 , the channel 33 of the operation section main body 3 is permitted to pass through the insertion block 22 in the perforation 20 of the annular section 21 , whereby the main body 3 can be assembled with the connection seat 1 .
- the shift body 2 is positioned in an unlocked position (or uninstallation position).
- the unlocked position is defined as a first position.
- the shift section 23 of the shift body 2 is moved to a position near the sidewall 16 of the arm 14 and the shift section 23 is aligned with the arm 14 , the insertion block 22 of the annular section 21 is driven to move from the channel 33 of the main body 2 into the end channel 34 (with reference to FIG. 1 ).
- the shift body 2 is positioned in a locked position (or installation position).
- the locked position is defined as a second position.
- the ridge section 252 slides along the sloped section 151 and the support section 153 to make the lever member 25 elastically swing the ridge section 252 in the protruding direction of the restriction section 15 (or in a direction to the bottom section of the connection seat 1 ). Accordingly, the ridge section 252 directly elastically passes over the protruding section (the support section 153 ) of the restriction section 15 to elastically latch into the insertion cavity 17 defined between the stop wall 152 and the sidewall 16 .
- one side of the ridge section 252 is automatically elastically backward stopped by the stop wall 152 , whereby the shift section 23 cannot be operated in the unlocked direction.
- the edge of the shift section 23 positioned on the other side of the ridge section 252 is also stopped by the sidewall 16 , whereby the ridge section 252 is restricted within the insertion cavity 17 in a locked state.
- the push/press section 253 In the locked state, when an operator presses the push/press section 253 in a direction to the arm 14 , the push/press section 253 is urged to drive the ridge section 252 to elastically swing in the protruding direction of the restriction section 15 (or in the direction to the bottom section of the connection seat 1 ) with the fulcrum section 251 serving as the fulcrum. Accordingly, the ridge section 252 is forced to pass over the restriction section 15 to unlatch from the insertion cavity 17 .
- the shift section 23 can be pushed from the second position to the first position (as shown in FIGS. 1 and 2 ) into an unlocked state (or uninstalled state).
- the shift body 2 drives the insertion block 22 to move from the end channel 34 back to the channel 33 to unlatch the channel 33 of the main body 1 from the insertion block 22 . Under such circumstance, the main body 3 can be detached from the connection seat 1 .
- the ridge section 252 elastically swings in the protruding direction of the restriction section 15 within the insertion cavity 17 (as shown in FIG. 7 ), the ridge section 252 swings in an arched path with the fulcrum section 251 serving as the fulcrum. Therefore, when the ridge section 252 gradually moves in the protruding direction of the restriction section 15 , there is a trend to urge the ridge section 252 to gradually push/press the stop wall 152 . At this time, due to the stop of the stop wall 152 in the reverse direction, the ridge section 252 will be slightly elastically bent in a direction to the sidewall 16 .
- the ridge section 252 will immediately release the elastic force to elastically move toward the sloped section 151 of the restriction section 15 (or the fulcrum section 251 ). Therefore, the ridge section 252 can pass over the stop wall 152 to elastically abut against the support section 153 . Accordingly, when the action force for pressing the push/press section 253 is released, the ridge section 252 is effectively prevented from again elastically latching into the insertion cavity 17 defined between the stop wall 152 and the sidewall 16 . This makes it easy to operate the shift section 23 from the second position back to the first position.
- the locking structure of the switch device of the present invention can be operated with less strength.
- the arm 14 of the connection seat 1 is free from the mouth section of the conventional switch device for achieving the locking/unlocking effect. Therefore, the entire structure is more completely enclosed. Accordingly, the present invention improves the shortcomings of the conventional switch device that when assembling/disassembling the main body, the operation is strength-consuming and the entire structure can be hardly completely enclosed.
- the fulcrum section 251 of the lever member 25 is disposed between the push/press section 253 and the ridge section 252 .
- the fulcrum section 251 can be alternatively disposed on the lever member 25 in a position in adjacency to the ridge section 252 .
- the distance between the push/press section 253 and the fulcrum section 251 is larger than the distance between the ridge section 252 and the fulcrum section 251 . This can enhance the strength-saving effect in operation of the lever member 25 .
- the fulcrum section 251 can be alternatively disposed on the lever member 25 in a position in adjacency to the push/press section 253 .
- the distance between the push/press section 253 and the fulcrum section 251 is smaller than the distance between the ridge section 252 and the fulcrum section 251 .
- This can increase the swinging angle of the ridge section 252 driven by the lever member 25 so as to increase the raising length of the ridge section 252 and the depth of the insertion cavity 17 . Under such circumstance, the security of the ridge section 252 latched in the insertion cavity 17 is enhanced.
